Hi Bert,
Please look your System.map and confirm it is generating the function
board_ws2812_initialize(). Something it is not even included because
some missing configuration.
You enabled DEBUG LED INFO, show you should see some messages in the
console if it was called, see: drivers/leds/ws2812.c
BR,
Alan
